Posting your lineup would help a bit so we could see whether or not you're stronger in pitching or batting.Assuming your batting and pitching are fairly equal, Price for McCutchen is a steal; offer him that and see if he accepts. If he doesn't, I still think Price + Marte for McCutchen favors you by a slight margin.

Yes thanks to big years by Darvish, Masterson you definitely can deal Price...Liriano won't be around on your team very logn (I'd stream that spot and then package Masterson+BJ UPton for a slightly better SP.
